Globally registers aUE::DerivedData::IBuildWorkerFactoryinstance for each platform that build workers can be supported. Users should include a  variable in their file path to indicate that this worker receipt can exist for any platform. If the receipt path does not include a  variable, then no attempt will be made to find variations of it for other platforms.
